  • Spring Handles Product Overview

  • NRH 4201-100 Spring Handle | SUS 304 Stainless Steel Handle with High Gloss Finish

    The NRH 4201-100 is a premium-grade spring handle​ that combines durability, functionality, and aesthetics. Crafted from SUS 304 stainless steel​ and finished with a sleek High Gloss Finishing, it offers superior corrosion resistance and a professional appearance. Integrated with a robust spring mechanism and a comfortable soft rubber grip, this handle features a 90-degree mechanical stop​ for stable lifting and an automatic spring-return action​ for space-saving storage. Weighing only 122g​ with a 245N (25kg) tensile load​ capacity, it is designed for reliable performance in demanding applications. Proudly bearing the NRH​ brand, it represents quality hardware from a trusted manufacturer.
    Primary Applications
    This handle is designed for high-quality applications where corrosion resistance, clean appearance, and reliable operation are required:
    • Premium Instrument Cases:​ Handles for precision measurement equipment, laboratory analyzers, and calibration standard cases.
    • Professional Audio/Video & Road Cases:High-end flight cases for mixers, amplifiers, and broadcast equipment.
    • Medical & Laboratory Devices:Sterilization containers, portable diagnostic units, and medical carts​ where hygiene and durability are critical.
    • Food Processing & Marine Equipment:​ Enclosures and cases in corrosive environments or where frequent cleaning is needed.
    • High-End Industrial Consoles:Control panels, server racks, and technical furniture​ requiring a sleek, durable handle.
    How It Works (Operation Principle)
    The handle operates on a precise spring mechanism. To use, simply pull the handle upwards; it will extend smoothly until it reaches the integrated 90-degree stop, locking into a stable position ideal for carrying. To store, release the handle—the internal spring automatically retracts it, allowing it to fold completely flat against the mounting surface. This provides a secure grip when needed and maintains a clean, low-profile appearance when not in use.
